#1384 testing defect

Reseeding can take place before the netDb is ready

Split from #1192.

While testing, I made my own i2pseeds.su3 file to reseed I2P in Tails. My i2pseeds.su3 contained 200 router infos and was hosted on my PC. I configured myself to be a reseed host, copied my certificate to the reseed directory and started I2P.

The I2P router was running within Tails in a virtual machine. The virtual machine was running on the same host as the makeshift reseed host.

9/21/14 8:40:05 PM ERROR [JobQueue 2/4] db.kademlia.IterativeSearchJob: We don't know any peers at all

After running for 38 minutes, I still didn't have any peers. The netDb in the console was empty, but the RIs were correctly placed into the 64 subdirectories.y

There were 4 exploratory tunnels listed and 4 client tunnels, but no peers.

I then restarted I2P. I immediately saw


  • Active: 2/2
  • Fast: 75
  • High Capacity: 102
  • Integrated: 91
  • Known: 199

Of course, after a few minutes I was able to access services within I2P.

With a normal installation and using our default reseed hosts, I am able to get find other peers and connect to I2P. With my single i2pseeds.su3 file I could not.

<zzz> looking at the ticket, the reseed was completed 2 seconds after startup. I think maybe it happened too fast
<zzz> like the netdb wasn't ready to hear about the reseed being done

Status: acceptedtesting

can't reproduce or completely understand what's happening, I don't see anything happening out of order, but non-volatile fields and the precise order in which we set them may have caused it.

Possible fixes to PersistentDataStore? in c1b10adca273a2e65028d9ac7e9e274531c3b902 0.9.17-8
